FIELD: oil and gas industry.
SUBSTANCE: according to the method, a template is set into the well bore. Manometer, flow meter and rotary valve are consequently connected to the template. The rotary valve is fully opened. Cement slurry is fed into the space between the template and the well bore. The feeding solution volume is set equally to the pre-calculated amount of the space between the well bore and the template. Air flow in the upper part of the template is monitored by a flowmeter. If the volume of air displaced by the cement slurry, the amount of space between the well bore and the template are exceeded, the rotary valve is closed by the template in half. The pressure in the upper part of the template is monitored with a manometer. If the manometer pressure exceeds the predetermined value, the rotary valve is fully closed.
EFFECT: improving efficiency of the method due to reduction of the time and material inputs connected to the well cementing.
